Invocie verificatio tolerances

Dear MM consultants,

I maintained PP tolerance for invoice in config ( OMR6) as Absolute and percentage basic.( both assigned )

i craeted Po and doine MIGO.

During MIRO when the price is different system is considering only absolute value not % value.

I tried with various prices, still picking teh absolute value.

Pl reply how to fix
